1.首先是运行脚本的时候报错，如下：
ft1.1: Traceback (most recent call last):
File "E:\meiyifen\productline\case_cashLoanMessage.py", line 10, in test_cashLoanMessage
change_user.changeUser().changeUser()
File "E:\meiyifen\warehouse\change_user.py", line 9, in changeUser
param.ock.firststeps()

return self.do_open(httplib.HTTPConnection, req)
File "C:\Python27\lib\urllib2.py", line 1198, in do_open
raise URLError(err)
URLError:

2.执行 adb devices 的时候出现乱码，如下：
List of devices attached
6&27fcf041&0&0003 device
